1. Isishwankathelo sePVC Compound Mixing Technology
1.1 Imigaqo esisiseko yePVC Compound Mixing
I-PVC i-compound mixing yinkqubo enzima yomzimba kunye neekhemikhali edibanisa ukuxuba okuqinileyo, Ukunyibilika, ukwenza iplastiki, ukucheba, kunye ne-homogenization. Eyona njongo iphambili kukusasaza ngokufanayo izongezo ezahlukeneyo kwi-PVC resin matrix, ukuphelisa iziphene zangaphakathi (njengamaqamza omoya, iagglomeration, kunye nokuhanjiswa kwecandelo elingalinganiyo) yomxube, kunye nokuphucula idigri yePlasitiki kunye nokusebenza kokusebenza kwekhompawundi, ukuze kwakhiwe isiseko esiluqilima sokusetyenzwa kokubumba okulandelayo (njenge-extrusion, isitofu sokubumba, ikhalenda) kunye nokusebenza kwemveliso yokugqibela.
Inkqubo yokuxuba iikhompawundi zePVC zidla ngokuhlulwa zibe zizigaba ezibini: ukuxuba okomileyo kunye nokunyibilika ukuxuba. Dry mixing is the initial stage, which mainly involves mixing PVC resin powder with various additives (such as stabilizers, izinto zokuthambisa, fillers, plasticizers for flexible PVC) in a high-speed mixer. The purpose of dry mixing is to make the additives uniformly adhere to the surface of PVC resin particles through the action of mechanical stirring and friction heat, and to preheat the mixture to a certain temperature, which is conducive to the subsequent melt plasticization. Melt mixing is the key stage, which is usually completed in extruders or internal mixers. Under the combined action of external heating and shear force generated by the screw (or rotor), the PVC resin particles are gradually melted and plasticized, kwaye izongezo zisasazwa ngakumbi kwi-resin matrix kwinqanaba lemolekyuli ukwenza inkqubo yokunyibilika efanayo kunye nezinzile.. Ekugqibeleni, ukunyibilika kukhutshiwe, igranulated okanye yenziwe ngokuthe ngqo kwiimveliso.
1.2 Izongezo eziphambili zePVC Compound Mixing
Ukusebenza kweekhompawundi ze-PVC kunqunywe kakhulu luhlobo, idosi kunye nesiphumo sokuxuba izongezo. Izongezo ezahlukeneyo zidlala indima eyahlukileyo kwinkqubo yokuxuba kunye nokucubungula kunye neemveliso zokugqibela. Ezi zilandelayo zizongezo eziphambili ezisetyenziswa ngokuqhelekileyo kwi-PVC yokuxuba:
1.2.1 Izinzisi:
I-resin ye-PVC ivame ukuthotywa kwe-thermal kumaqondo aphezulu (ngaphezulu kwe-100℃), nto leyo eya kukhokelela kumbala (ukusuka kumhlophe ukuya kumthubi, ntsundu, nokuba mnyama), ukuncitshiswa kweempawu zoomatshini kunye nokulahleka kwexabiso lokusetyenziswa. Ngoko ke, i-stabilizers kufuneka yongezwe kwiikhompawundi ze-PVC ukuphucula ukuzinza kwazo kwe-thermal. Common PVC stabilizers include lead-based stabilizers, calcium-zinc composite stabilizers, barium-cadmium stabilizers, and organic tin stabilizers. Phakathi kwabo, calcium-zinc composite stabilizers are widely used due to their environmental friendliness, non-toxicity, and good thermal stability, which are in line with the global environmental protection requirements for plastic products.
1.2.2 Iiplastiki zeplastiki:
Plasticizers are mainly used in flexible PVC compounds to reduce the glass transition temperature of PVC resin, improve its flexibility, toughness and processability. They can penetrate into the molecular chain of PVC, weaken the intermolecular force, make the molecular chain easy to move, thus making the PVC compound soft and easy to process. Common plasticizers include dioctyl phthalate (DOP), dioctyl terephthalate (DOTP), diisononyl phthalate (DINP), and epoxy soybean oil. Phakathi kwabo, DOTP has the advantages of environmental protection, low volatility, and good compatibility with PVC, and is widely used in high-grade flexible PVC products (such as medical hoses, food packaging films).
1.2.3 Izigcwalisi:
Fillers are added to PVC compounds to reduce production costs, improve the rigidity, ubulukhuni, wear resistance and dimensional stability of products, and adjust the density of compounds. Common fillers include calcium carbonate (light calcium carbonate, heavy calcium carbonate), umgubo wetalcum, kaolin, and carbon black. Calcium carbonate is the most widely used filler due to its low price, abundant sources, and good compatibility with PVC. The addition of an appropriate amount of calcium carbonate can not only reduce costs but also improve the processing fluidity and impact resistance of PVC compounds.
1.2.4 Izithambisi:
Lubricants are used to reduce the friction between PVC resin particles, phakathi komxube kunye nezixhobo (njengodonga lwangaphakathi lomxube, isikrufu se-extruder), naphakathi kokunyibilika nokungunda, ukuze kuphuculwe ukusetyenzwa kwamanzi kwikhompawundi, ukuthintela izinto ekubambeleleni kwisixhobo, kwaye uqinisekise inkqubela phambili egudileyo yenkqubo yokuxuba kunye nokubumba. Izithambiso eziqhelekileyo ziquka i-stearic acid, calcium stearate, i-zinc stearate, kunye neparafini. Ngokwendlela yokusebenza, izinto zokuthambisa zinokwahlulwa zibe zizithambiso zangaphakathi kunye nezithambiso zangaphandle. Izithambisi zangaphakathi zinokunciphisa ukukhuhlana phakathi kwamakhonkco emolekyuli ePVC, ukuphucula ukusebenza kakuhle kweplastiki; i-lubricants yangaphandle inokwenza ifilimu yokuthambisa phezu kwezinto eziphathekayo, ukunciphisa ingxabano phakathi kwezinto kunye nezixhobo.
1.2.5 Izilungisi:
Izilungisi zongezwa ukuphucula iipropati ezithile ze-PVC compounds, njengokumelana nempembelelo, ukumelana nobushushu, kunye nokungafihli. Izilungiso eziqhelekileyo ziquka i-acrylonitrile-butadiene-styrene (ABS) intlaka, i-methyl methacrylate-butadiene-styrene (MBS) intlaka, i-polyethylene ecocekileyo (CPE), kunye ne-acrylic resin. Umzekelo, I-MBS resin inokuphucula kakhulu ukuchasana kwempembelelo yeekhompawundi eziqinileyo zePVC, ukwenza ukuba zilungele ukuveliswa kwemibhobho yeplastiki, iiprofayili, kunye neendawo zokubumba zokutofa ezifuna ukuqina okuphezulu.
1.3 Ukubaluleka kwePVC Compound Modification kunye neGranulation
Kwiimeko ezininzi zokusetyenzwa kwePVC, I-resin ye-PVC kufuneka iguqulwe kwaye ihlanjululwe kuqala ngaphambi kokuba kuqhutywe ukubunjwa okulandelayo. Oku kungenxa yokuba igranulation elungisiweyo inokuzisa iingenelo ezininzi ezicacileyo:
Ekuqaleni, iphucula inqanaba lePVC yePVC. Ngokusebenzisa isenzo esidibeneyo sokuxuba okomileyo kunye nokuxuba ukuxuba kwinkqubo ye-granulation, Amasuntswana e-resin e-PVC anyibilike ngokupheleleyo kwaye afakwe iplastiki, kwaye izongezo zisasazwe ngokufanayo, ekhusela iingxaki zeplastiki enganeleyo, ukuhanjiswa kwecandelo elingalinganiyo, kunye neziphene zangaphakathi ekubunjweni ngokuthe ngqo kwe-resin ecocekileyo, ngaloo ndlela kuphuculwe ukusebenza kwenkqubo yezinto.
Isibini, yenza lula inkqubo elandelayo yokucubungula. I-PVC granules emva kokuguqulwa kunye ne-granulation inobukhulu obufanayo, fluidity elungileyo, kunye nokusebenza okuzinzileyo. Zingasetyenziswa ngokuthe ngqo kwi-extrusion, isitofu sokubumba, ikhalenda, vuthela ukubumba kunye nezinye iinkqubo zokubumba ngaphandle kokuxuba okongeziweyo okanye ukulungiswa kwangaphambili, okunciphisa inkqubo yemveliso, iphucula ukusebenza kakuhle kwemveliso, kwaye inciphisa ukuqina kwabasebenzi.
Isithathu, iqinisekisa ukuzinza komgangatho wemveliso. Ukusebenza kweegranules zePVC ezilungisiweyo kuzinzile, enokuthi igweme ukuguquguquka kokusebenza kwemveliso okubangelwa ukuxuba okungafaniyo kwezongezo ekubunjweni ngokuthe ngqo, thus ensuring the consistency of product quality and reducing the product defect rate.
Isine, it expands the application scope of PVC. Through targeted modification (such as adding different modifiers, iiplasticizers, kunye nezihluzi), PVC compounds with different properties can be prepared, which can meet the requirements of different application fields. Umzekelo, rigid PVC granules with high rigidity and impact resistance can be used in the production of plastic pipes and profiles; flexible PVC granules with good flexibility and softness can be used in the production of hoses, iintambo, kunye neefilimu zokupakisha; flame-retardant PVC granules can be used in the production of electrical and electronic products.
